Application filed July 23, 1897. Serial No. 645,726. (No model.)

To all whom it may concern.-

Be it known that We,WILLIAM D. HEEBNER and NATHANIEL METZ, citizens ofthe United States, residing at Lansdale, in the county of Montgomery andState of Pennsylvania, have invented certain new and useful Improvementsin Shredding Attachments for Feed- Cutters, of which the following is aspecification.

Our invention relates to machines for shredding and dividing cornstalksand it consists, first, of a peculiar cutter-bar, and, second, in thecombination of the said cutter-bar with the feed-rolls and cutter-headof a cutter, all as fully set forth hereinafter and as illustrated inthe accompanying drawings, in which Figure l is a perspective view ofour improved cutter-bar in one form in which it may be made, and Fig. 2is a sectional View illustrating the arrangement of the bar in a cutterhaving a cutter-head and feed-roll.

The cutter-bar A is suitably constructed for attachment to any desiredstyle of machine, or, for instance, to machines of differ ent styleswhere it can be substituted for the ordinary cutter-baras,forinstance,in shredding-machines, shredders and snappers, or feed-cutters,in different styles of all of which machines cutter-bars are employed.These cutter-bars generally consist of plain bars, against the upperforward edges of which the cutter-head or shredding-head operates, thecutter-head consisting generally of a shaft carrying a series ofinclined curved knives and the shredder-head consisting frequently ofsaws sometimes set at an angle to the shaft.

Our improved cutter-bar or shredder-bar consists of a plate adapted forattachment to the machine opposite to the lower feed-r0112, as shown inFig.1, and between the latter and the cutter-head B, whatever may be thecharacter of the latter. Near the lower part of the bar is astraight-edge m, which constitutes the cutting edge,'and between thisedge and the upper part of the bar is a curved or fiat face a, and fromthis face may project a series of cutting projections 4: 4 at, shown asarranged in rows and alternating, presenting a series of cutting-teethabove the cutter-bar.

Above the face 0 the bar is rounded off to form a curved edge e,connecting the face 0 and the horizontal face of the bar, and from thelatter extend ears 5 5, which are perforated to receive the bolts bywhich the bar is attached'to the machine.

The stalks are passed, as usual, between the feed-rolls 1 2, which maybe corrugated or plain and of any desired size, and as they pass overthe rounded edge e of the bar, instead of being cut off sharp upon saidedge, as usual, they are bent by the action of the cutter-head B downonto the face 0 and are shaved and cut by the cutters, and when the faceis provided with teeth 4 4 4, the latter,

when the stalks are carried downward and forward, divide the stalkslongitudinally, breaking, splitting, and shredding the same, and whenthey reach the cutting edge a: they are then cut or broken off betweenthe said edge and the teeth or knives of the cutterhead.

By the application of this device to ordinary cutters we can convert thelatter into a shredder and can cut the corn product into broken, torn,split, and shredded pieces, preparing it-for use instead of hay, or ifused for bedding it will better absorb the liquid manure than the fodderwhich is cut off square, as usual. The Whole structure A may consist ofone piece of metal or of two parts, a blade of steel f being bolted orotherwise secured to the body portion, which may be of cast metal, andthe cutting edge being at the top of the steel blade.

It will be obvious that the cutter or shredder bar A may be made of anysuitable size, adapted to any kind of machine, either to machines inpermanent use or those especially constructed for the purpose.

Without limiting ourselves to the precise construction and arrangementof parts shown, we claim as our invention 1. A shredding and cutter barconsisting of a bar adapted for attachment to a machine provided with acutter or shredder head, having a cutting edge as, and above the lattera series of teeth at, t, at, substantially as and for the purpose setforth.

2. A cutter-bar provided with a cutting edge 00, a series of teeth abovesaid edge and a rounded edge e, at the top of the bar, substantiallyasand for the purpose set forth.

3. The combination with the feed-rolls and cutter-head of ashredder, ofa cutter-barhaving at face 0, a rounded edge above said face, andcutting edge 00 below the same, substantially as described.

4:. The combination in a cutter, of a cutterhead B, and feed-rolls 1, 2,and a cutter-bar having teeth i, at, 4, and a cutting edge 00 below thesaid teeth, substantially as set forth.

5. The combination in a cutter, of a cutternames to this specificationin the presence of 20 two subscribing witnesses.
